SageForum for UK versions of Sage 50- Help and support.

I am using version 12 and have just changed from std vat to cash vat.

I have a supplier invoice and payments on account that I would like to allocate off but am getting the following message

"there is a mismatch in the net/tax elements of the payments selected. Please ensure that the tax codes of any credits notes/payments on account are matched against invoices with which they are to be allocated to"

Can you help please??

The tax code of the items do not match.


In Sage under standard VAT a payment on account is T9 under cash accounting it is T1.


You need to reverse the payment on account transaction (as T9) and then re-enter it as a new payment and match it.
